There are tools a-plenty for figuring out whether to rent or buy in your area, but they require multi-step research: average house prices, average rents, and more. Real estate datamine Trulia figured out the rent/buy ratio, then mapped it for your convenience.

The Rent:Buy Ratio is calculated by using the median list price compared with the median rent on two-bedroom apartments, condos and townhomes listed on Trulia.com.

Some of the cities won't make you bat an eyelash—New York and Los Angeles are places to rent, and Nashville is a place to buy. But the math on Honolulu works out favoring buying, perhaps because of the price seasonal landlords know they can get. If you want to dig a little deeper, the interactive map can map and list lots of other data for a city, including tax averages, unemployment, average rent price, and many more.
